I have someone interested in leasing Yankee but they want to jump him. He's got the heart for it, he's such an honest horse but what I want to know is conformationally, could he do it without risking injury? I know he's got pretty steep back legs but I don't know how that would affect a horses jumping ability...I know NOTHING about jumping. He has put on quite a bit of weight since these pictures were taken and has been building muscle. Thanks
With the angles critique is a little difficult, it would be easier to say if he was squared up with his neck up. From what I can see:
-he has long thin pasterns especially in the front, be careful with applying stress here.
-his hind angle is rather steep/straight.
-he appears to have a downhill build.
-possibly over the knee in the front.
-he will need more top line muscle and weight prior to jumping.
From looking at him, I would guess he could jump 2-3 feet with ease in competition as long as you take the necessary precautions (that come with jumping any horse) to keep things safe and fun.
